' Letters Patent No. 90,665, dated .Tune 1, 1869.

IMPROVEMENT 1N cHURNs.

A The Schedule referred to in these Letters Patent and making part of the sarna.l

To all whom it may concern Be it known/that I, GAYLORD J ONES, of the city of Grand Rapids, county of Kent, and State of-Michigan,

have invented a new and useful Atmospheric Churner sel-'containing milk or cream, and to this end I construct the apparatus hereinafter described.

The device I have invented consists of two bellows,

v supported by a frame-work and legs, and worked by the alternate raising and lowering of the levcr\1), as shown in fig. 2. Itis composed of abody, in two compartments, and supported by legs. Ilhe bellows are shown in iig. 2 by E and F, and they are made of leather, which is nailed to the edge of top and bottom pieces P, rabbeted for that purpose, which are made of such size as to move easily in the compartment-s in which they are placed.

The lower pieces are fastened to the body of the machine, by means of screws, inserted from beneath. Each bellows is furnished with two valves, G I and H J, one opening upward and the other downward.

As the bellows E is raised, air is drawn into it through the receiving-passage It, which is usually an inch-auger hole, the valve G being raised.

When the bellows is compressed, as shownby F, the receiving-passage is closed by the valve H covering it, and the air is forced out through the discharging-passage Q, the valve J being depressed.

It will thus be seen, that by operating the machine 'a constant dow of air will be forced into the space l,

and thence downward through the tube L.

K is a funnel-shaped piece of tin, attached to the body of the machine, and extends downward an inch or thereabouts, in the form of a tube.

The tube L and perforated cone M are made of tin, and the latter should be of such size as to nearly ill the vessel Icontaining the milk or cream to be churued. Itis used to prevent sputtering.

For ordinary purposes, the case enclosing each bellows should be about six Vinches by eight inches, and live inches deep. The valves arc made of leather, or other suitable material, and the body and legs of the machine of wood.

O is a fixed standard, upon which the level-1) plays, and

A B are the rods, which attach the lever to the bel-v lows.

The top, O, is held to 'its place by the hook P.

To use my invention, I place it ovcrachurn or other receptacle containing cream or milk, and insert the tube L in the receptacle, so that its lower end will reach' within about two'iiiches of the bottoni.

The perforated conc M, which is Vattached tov the upper end of the tube, should be placed at or near the suriacefof the cream or milk.

'lhe tube L should be about one-half inch in diameter, and is made to fit closely to the outside of the tube-part of the funnel-shaped tin K.

I use no other means for bringing butter than the forcing a current of air into the vessel containing the vmilk or cream to be churned, at or near the bottom,

and allowing it to rise to the surface and escape.

l am well aware of the patent granted to Robert McOutcheon, for an atmospheric churn, June 2, 1857, i

and this I do not claim; but

What I claim as new, and desire to secure by Letf ters Patent, isi l. 'lhe apparatus, consisting of the bellows E F, operated by means of lever D and arms A B, valves G H I J, andk funnel K, when operating to churn cream in any vessel, independent of and separate from the above apparatus, as and for the purposes described.

2. In combination with the above, the perforated cone M, substantially as and for the purposes set forth.

In testimony that I claim the above, I have hereunto set my hand and seal, this 15th day of August, A. I). 1868.
